Grid method of multiplication explained

The grid method is a way of teaching multiplication that is used in primary schools. Pupils move on from an array to the grid method. It is also used for teaching times tables.

You need an empty number square.

To calculate 35 × 7, set it out in a grid like this:

Multiply each pair of numbers and write them in the grid. Then add the two products (ie answers to the multiplications) to find the answer.

The grid method can also be used for more difficult multiplications, such as 35 x 26.

If children are not familiar enough with their times tables to complete the grid in this way, the numbers can be broken down further eg 35 can be broken into 10, 10, 10, 5; 26 can be broken into 10, 10, 6.
